90 Section I: Using the Menus Interface

Enabling or
Disabling a Port
Trunk
This procedure enables and disables a port trunk. Note the following
before performing this procedure:
ˆ Do not enable a port trunk until after you have configured the trunk on
both switches.
ˆ Do not connect the cables to the ports on the switches until after you
have configured and enabled the trunk on both switches.
Note
If you are disabling a port trunk, be sure to first disconnect all cables
from the ports of the trunk. Leaving the cables connected can create
loops in your network topology because the ports of a disabled port
trunk function as normal network ports, forwarding individual
network traffic.
To enable or disable a port trunk, perform the following procedure:
1. From the Main Menu, type A to select Advanced Switch
Configuration.
The Advanced Switch Configuration Menu is shown in Figure 21 on
page 87.
2. From the Advanced Switch Configuration Menu, type T to select
Trunk Configuration.

3. From the Trunk Configuration Menu, type S to select Set Trunk
Status.

4. Type the number of the trunk group you want to enable or disable and
press Enter.
The following prompt is displayed:
Set trunk group n status (A/P/M/D)>
5. Type M to enable a manual trunk, or D to disable the trunk.
